Answers Week 28

1: Racing Rules
Blue and Red are both reaching on starboard to the Boat End for the start. Just before the gun, blue luffs up to the line, cutting off Red’s approach. Red protests.

Does Red have a valid protest? YES In accordance with rule 16.1 Blue may not change her course so late, because Red by this time no longer has room to keep clear. Blue should have luffed earlier, if she wanted to close the gap. There is no rule, that requires of a boat (here: Red) to anticipate an action of another boat (here: Blue’s luff towards the starting line), even if this action is to be expected.
